4.1.1. Construction Land Suitability

Areas with high suitability for construction accounted for the highest proportion (58.39%) and were concentrated in Shanghe county and Jiyang, Tianqiao, Huaiyin, Shizhong and Lixia districts, as well as the northern Licheng district, northern Zhangqiu city, western Changqing district and Pingyin county (Figure 3). Of these, Tianqiao, Huaiyin, Shizhong and Lixia districts are the central districts of Jinan with developed transportation and obvious regional advantages. Shanghe county and Jiyang district are in the North China Plain where the terrain is flat and geological disasters do not occur easily. Areas with low construction land suitability accounted for the smallest proportion (17.23%) and were mainly distributed in the east of Changqing district, the south of Licheng district, the south of Zhangqiu city and the north of Laiwu district. These areas are in the southern mountainous region and have high terrain and steep slopes, are prone to geological disasters, are far away from towns, have inconvenient transportation and have low suitability for use as construction land. The proportion of areas with medium suitability for construction was 24.38% and were relatively spatially scattered.
